Ok So after the first post got deleated here we go on round 2 again I will explain the following
Materials
Guidecoat
Sanding
Intro to masking
Spray booth workings
How to clay bar
how to remove overspray
how to remove a hair from paint(yeah i know wtf right)
Ok materials
DA Sanders I use Ingersoll Rand I own 4 and have never had a problem with them in 5 years. I had said it in the other post you should find a good quality one. The reason I have so many is that there are different throws as far as the action of it. The larger throws are used for bodywork while smaller throws are used for resurfacing ie: painting
One other material used with a DA sander that I highly suggest is an interface pad.
these go between the sander and paper they even out the pressure so you dont burn down high spots aswell as reduce swirls.
With mention to swirls the next topic is paper. Besically you get what you pay for buy cheap paper better buy a lot of it.
On the right is regular "SandPaper" on the left is paper by a brand named Mirka that is far superior. I use both as it depends on application what i need. If its something I dont care about or wetsanding I use reg paper if it is something that needs to be nice i use mirka paper.
With mention to sanding I also have a small multi function tool that works great to get into tight areas aswell as for doing bumper covers
Pt2 Guide Coat
When Sanding its nice to know when to stop so that when Guide Coat comes into play basically you spray it on the surface to both show you where you have sanded aswell as low spots.
Asfar as how to apply remember its guide so dont spray it like that just mist it on evenly
kinda like this
ok so as you sand it will sand away this allows you to see low spots here is the best pic i could take to show you how it works and no this isnt me there was shit under the primer
This is what it looks like to sand away the guide coat basically sand it all off evenly and it will make your car straight.
Pt3 Sand for paint.
First remove the emblems and glue with a flat tool an an eraser wheel or a little solvent
Materials needed are your fav DA and both 220 and 320 grit paper.
start with the rock chips you want to sand them out and the way to make them smooth is to create what i like to call an asshole. you want to sand over the chip with 220 till it starts to break down then move in an x patten until its creates the asshole working it until the area around it is a gradual slope all around the area like so.
Now that you have assholes all over its time to sand the whole surface with 320 this gives a nice surface for both the primer and paint to bite into. speaking about primer for most jobs a 1k primer will do. this is refered to as a filler primer.
ok now depending on how comfortable you are with a DA sand the car staying about 1/2" away from anything you dont want to paint ie headlights mouldings etc. sand off all the orange peel 320 will knock it down quite nicely. get a nice powerdy surface.
work around the car from front to back staying away from everything you dont want to paint. now once you get done with the DA its time go go back by hand with either a scuff pad(garbage) or a peice of 320 wrapped around a scuff pad(awesome)
once you sand all the areas you end up with a car ready for paint.
Now to Mask now this is just a intro talking about Jams and a trunk for you 4dr guys.
Now I know pry no one has a masking machine like such
However newspaper and some masking tape will do just fine.
Start by taping the door about a 1/4" from the edge much like so
then do the inside jam its pretty much the same for both coupe and 4dr guys.
now for the trunk its also pretty much the same pretty much like such
I know this is just the surface of masking but i ran out of time at work today and this is as far as I got. Now onto something more fun.
How our booth works. Ok as far as drying the air that comes in we use a large desicant for main drying purposes
then in our booth is our regulator as well as the filter. this is made by Devillbis and its top notch shit
Btw I spray at around 30psi depending on the gun I use.
Here is a pic of the booth and the oven(no it wont cook a pizza but will warm up cookies awesome)
Here is a pic inside the booth if you look at the celing its full of filters this is refered to as an updraft booth it works but def not the best but eh I like it.
Ok Enough of that
What happens if after you paint a car you get a lot of paint on areas that are already painted well now you need to clay bar(no not playdough) any 3M or Mothers bar will work nicely. Its hard to see in the pics but this fender has a lot of oversprayed clear on it
Ok now you have to spray the area with water and be generous
Now whip out your clay bar I use a 3M one,
Toss it on and rub it
You can feel the clay bar drag for 2 reasons one is there is surface imperfections 2 is that there isnt enough water(you be the judge)
You want to feel the bar just glide with little effort over the surface to let you know everything is off the surface.
Say you got over spray on plastic peices no biggie here is a trick I use.
Get your self some compound
put a small amount on a rag
then take and rub the area lightly you will feel the compound bite in then rub it off and wolla no more clear coat on your mirrors
Now suppose you didnt quite mask off everything quite as good as you want like such
now you only need 2 items one is a q-tip the other is thinner
its pretty self easy just use lots of q tips and the paint will soften then eventually dissolve.
Ok now for some fun suppose someone paints a car and gets a pube in the paint(well just hair in general)
take more water and some 2000 grit paper
now sand gently till you get the hair to lift out this one didnt take to much effort but still messed some shit up.
Now to use one of my fav tools my mini buffer
buff away with a little compound and it will shine like the sun.
I know it looks weird but its a shadow of me taking a pic.
Ok now for all you mullet men out there here are some before and after a camaro that i painted for some mexican guy today
Ok No hopefully this one wont be taken down.
Btw this moment brought to you my Mr. Boston Vodka and Lemonade
